nettl and hp-ux port aggregation

[Kenneth_18]

I was trying to trace a packet using the nettl command below:

#nettl -tn 0x300000000 -e NS_LS_IP however when I searched for the ip packet with the corresponding ip address I could not find it in the trace. When I do a netstat -an, I can see that there is already an existing session between the server and the host in question.

I later realized that the connection to that partucluar host uses port aggregation.

Was the reason I was getting no packets was because nettl can not trace packets going through aggregated lan interfaces?

How can I trace ip packets going through a port aggreated interface using nettl?

Thanks in advance!

The port aggreation should not affect it. Not very confortable with this, but it would be a better idea to put the ip _address to watch in filter file and check for traffic on that ip_Address.

port aggregation should not affect IP packet tracing. In the command you run, the nettl tracing subsystem is "ns_ls_ip", which is not affected by port aggregation.
I run the same command on my system, I did see IP traffic to and from port aggregations. ( I am running 11i v2, but I don't think that matters to nettl. BTW, what is the OS version of your system?)

I triply concur.. APA should'nt make any difference.

Yup you're all right. I just tested again by also pinging the host in question and indeed I can see the ping packets. This is a case of phantom packets as I'm sure the packets are being sent but I just can't seem to trace them.
